Technical Field

[0001] This utility model patent relates to the field of steel structure technology, specifically to a magnetically positioned curtain wall support connection structure. Background Technology

[0002] In prefabricated steel structure buildings, the stability and rust prevention performance of curtain wall connection devices are crucial, serving as fundamental prerequisites for ensuring stable installation and normal use of the building's curtain wall. To facilitate the rapid installation of the curtain wall steel structure support system, a pre-fixed structure is typically used, where the beams are pre-fixed to the columns before welding. This method not only helps improve positional stability during welding but also facilitates smooth welding operations.

[0003] Patent CN116163417A discloses a prefabricated steel structure building curtain wall connection device, including a vertical support beam, a horizontal support beam on the outer side of the vertical support beam, a first pre-installation piece on the outer side of the vertical support beam, a second pre-installation piece on the outer side of the vertical support beam, and an installation block located between the two first and second pre-installation pieces on the outer side of the vertical support beam. The first and second pre-installation pieces are welded to the vertical support beam at their connection points using welding rods. An installation block is installed between the upper and lower second pre-installation pieces and the first pre-installation pieces. The cooperation of the connecting block ensures the stability of the connection between the installation block and the first and second pre-installation pieces, ensuring stable stacking of the vertical support beams during transportation and facilitating the welding of pre-installation grooves during use.

[0004] However, the support structure in the above technology still has the following problems: during the process of fixing the pre-installation piece to the outside of the shaped column with bolts, the pre-installation piece may shake or shift on the outside of the column as the bolts rotate, resulting in the installation position being misaligned with the original planned installation position and poor stability of the installation operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model patent provides a magnetic positioning curtain wall support connection structure, which improves the installation and fixing efficiency of the support structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A magnetically positioned curtain wall support connection structure includes a U-shaped column and several horizontal beams, and several connecting components arranged circumferentially along the U-shaped column. Each connecting component includes two connecting handles arranged symmetrically at the top and bottom. The connecting handles include a vertical part and a horizontal part. The vertical parts of the two connecting handles are both attached to the side wall of the U-shaped column. The horizontal parts of the two connecting handles are connected to the same insert ring on the side away from the U-shaped column. The insert ring is adapted to the end of the horizontal beam. The horizontal beam is inserted into the insert ring. The insert ring is spaced apart from the U-shaped column, thus forming a structural gap.

[0007] As a preferred embodiment, a further technical solution of this utility model is: Preferably, a limiting plate is fixedly connected to the vertical end of the connecting handle away from the horizontal end, and a positioning groove is provided on the limiting plate; a strong magnetic block is detachably connected in the positioning groove; the connecting assembly is magnetically fixed to the outer wall of the mouth-shaped column by the strong magnetic block.

[0008] Preferably, a pull ring is fixedly connected to the outside of the strong magnetic block.

[0009] Preferably, the connecting handle is also provided with two side ribs at intervals, the side ribs connecting the vertical part and the horizontal part.

[0010] Preferably, the two side ribs together with the vertical and horizontal parts form a recessed cavity, and the vertical part is also provided with several bolts, the threaded rods of the bolts passing through the vertical part and the mouth-shaped column in sequence.

[0011] Preferably, a foam block is inserted into the inner cavity of the mouth-shaped column, and the threaded rod of the bolt passes through the vertical part and the mouth-shaped column in sequence before being inserted into the foam block.

[0012] Preferably, it also includes a protective shell, with a mounting hole through the bottom of the protective shell, the threaded shank of the bolt passing through the mounting hole, the bolt nut located inside the protective shell, and a sealing cap connected to the side of the protective shell away from the mounting hole.

[0018] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] Please see Figures 1 to 5 A magnetically positioned curtain wall support connection structure includes a U-shaped column 1 and several horizontal beams 2. The structure is characterized by further including several connecting components 3 arranged circumferentially along the U-shaped column 1. Each connecting component 3 includes two symmetrically arranged connecting handles 32, each handle 32 having a vertical portion and a horizontal portion. The vertical portions of both connecting handles 32 are fitted against the side wall of the U-shaped column 1. A common insert ring 31 is connected between the horizontal portions of the two connecting handles 32 on the side away from the U-shaped column 1. The insert ring 31 is adapted to the end of the horizontal beam 2, and the horizontal beam 2 is inserted into the insert ring 31. The insert ring 31 is spaced apart from the U-shaped column 1, thus forming a structural gap.

[0020] like Figures 1 to 5 As shown, the magnetic positioning curtain wall support connection structure in this utility model patent is similar to existing building curtain wall support structures, such as the prefabricated steel structure building curtain wall connection device disclosed in patent publication number CN116163417A. The main improvement of this utility model patent lies in improving the convenience of pre-fixing the support structure. Specifically, as shown... Figures 1 to 5As shown, a limiting plate 41 is fixedly connected to the vertical end of the connecting handle 32 away from the horizontal end. A positioning groove 401 is provided on the limiting plate 41. A strong magnetic block 4 is detachably connected to the positioning groove 401. The connecting component 3 is magnetically fixed to the outer wall of the U-shaped column 1 by the strong magnetic block 4. In use, the magnetic positioning curtain wall support connection structure of this utility model patent is magnetically fixed to the outside of the U-shaped column 1 by the upper and lower strong magnetic blocks 4, which can realize the quick connection of the connecting component 3 on the outside of the U-shaped column 1, thereby quickly completing the pre-fixation of the connecting component 3 on the outside of the U-shaped column 1, which facilitates subsequent welding or other installation and fixing operations. It eliminates the need to hold the connecting component 3 for connection and installation, greatly improving the installation convenience of the support structure.

[0021] The insert ring 31 is located between the two connecting handles 32. The two connecting handles 32 are magnetically attracted to the outside of the mouth-shaped column 1 by two strong magnetic blocks 4. At this time, there is a certain distance between the insert ring 31 and the mouth-shaped column 1. Then, the connecting handles 32 can be welded and fixed to the mouth-shaped column 1. After the fixing is completed, the end of the crossbeam 2 is inserted into the inside of the insert ring 31 and the end of the crossbeam 2 is welded and fixed to the mouth-shaped column 1. The installation of the entire support structure is completed. The magnetic fixing method of the strong magnetic blocks 4 makes it unnecessary for the installer to hold the connecting component 3 during welding. At the same time, it can reduce the possible shaking of the connecting component 3 during the welding process, improve the stability of the welding position of the connecting handle 32 and the mouth-shaped column 1, avoid the misalignment or displacement of the connecting handle 32 on the outside of the mouth-shaped column 1, improve the welding quality, and ensure that the end of the crossbeam 2 fits more closely with the contact surface of the mouth-shaped column 1 after the crossbeam 2 is inserted from the insert ring 31, thus ensuring the welding quality of the subsequent contact position between the crossbeam 2 and the mouth-shaped column 1.

[0022] like Figures 1 to 4 As shown, a pull ring 42 is fixedly connected to the side of the strong magnetic block 4 away from the limiting plate 41. The pull ring 42 allows the strong magnetic block 4 to be removed from the positioning groove 401 more smoothly and conveniently.

[0023] The setting of the limiting plate 41 and the positioning groove 401 facilitates the disassembly and installation of the strong magnetic block 4 and the connecting handle 32. When pre-installation is required, the strong magnetic block 4 can be placed in the positioning groove 401. The magnetic force of the strong magnetic block 4 on the mouth-shaped column 1 will press and fix the limiting plate 41 to the outside of the mouth-shaped column 1, and fix the connecting handle 32 to the outside of the mouth-shaped column 1. After the connecting handle 32 is welded and fixed, the strong magnetic block 4 can be removed from the positioning groove 401, so as to achieve the reuse of the strong magnetic block 4 and avoid the waste of the strong magnetic block 4.

[0024] Two side ribs are also spaced apart on the connecting handle 32, connecting the vertical and horizontal parts, thus strengthening the overall strength of the connecting handle 32. The two side ribs, together with the vertical and horizontal parts, form a recessed cavity 301. Several bolts 33 are also provided on the vertical part, with the threaded shanks of the bolts 33 passing through the vertical part and the mouth-shaped column 1 in sequence. The recessed cavity 301 facilitates the installation of the bolts 33 by construction personnel. After welding the connecting handle 32 to the outside of the mouth-shaped column 1, the bolts 33 can be used to reinforce and fix the connecting handle 32 to the mouth-shaped column 1, further increasing the connection strength between the connecting handle 32 and the mouth-shaped column 1.

[0025] like Figures 1 to 3 As shown, a foam block 5 is inserted into the inner cavity of the bevel-shaped column 1. The threaded shank of the bolt 33 passes through the connecting handle 32 and the bevel-shaped column 1 before being inserted into the foam block 5. Before screwing the bolt 33 into the bevel-shaped column 1 and the connecting handle 32, the foam block 5 can be inserted from the top of the bevel-shaped column 1 inwards, filling the installation position of the bolt 33. When the threaded shank of the bolt 33 penetrates into the inner side of the bevel-shaped column 1, the threaded shank is inserted into the foam block 5. The foam block 5 wraps around the threaded shank inside the inner cavity of the bevel-shaped column 1, which can isolate the threaded shank from the air as much as possible, thereby reducing the corrosion of the threaded shank by moisture in the air, which would cause rust damage to the threaded shank and improve the stability of the bolt 33 in use.

[0026] like Figures 1 to 5 As shown, it also includes a protective shell 6. A mounting hole 601 is provided through the bottom of the protective shell 6. The threaded shank of the bolt 33 passes through the mounting hole 601, and the nut of the bolt 33 is located inside the protective shell 6. A sealing cap 61 is connected to the side of the protective shell 6 away from the mounting hole 601. Before screwing the bolt 33 into the connecting shank 32 and the orifice-shaped column 1, the threaded shank of the bolt 33 is first inserted through the mounting hole 601 of the protective shell 6, so that the nut of the bolt 33 is inside the protective shell 6. Then, the bolt 33 is screwed into the connecting shank 32 and the orifice-shaped column 1. After the bolt 33 is tightened, the sealing cap 61 is placed on the protective shell 6, thus completely enclosing the nut of the bolt 33 inside the protective shell 6, isolating the nut of the bolt 33 from the air. This prevents the nut from corroding due to contact with moisture in the air during long-term use, improving the structural stability of the bolt 33.

[0027] like Figure 5 As shown, a sealing ring 62 is fixedly connected to the side of the sealing cover 61 near the protective shell 6. The outer diameter of the sealing ring 62 is adapted to the inner diameter of the protective shell 6. When the sealing cover 61 is placed over the opening of the protective shell 6, the sealing ring 62 is pressed against the inside of the protective shell 6. The friction between the sealing ring 62 and the inside of the protective shell 6 allows the sealing cover 61 to be stably placed over the opening of the protective shell 6.

[0028] like Figure 4 and Figure 5As shown, an elastic piece 7 connects the protective shell 6 and the sealing cover 61, with both ends of the elastic piece 7 fixedly connected to the protective shell 6 and the sealing cover 61, respectively. The sealing cover 61 and the protective shell 6 are connected by the elastic piece 7, which can prevent the sealing cover 61 from falling off and being lost.

[0029] It is worth noting that when the connecting handle 32 is attached to the outside of the bevel post 1, a structural gap is left between the insert ring 31 and the bevel post 1. This gap allows the welding equipment (such as welding rods) to extend from the outside of the insert ring 31 to the contact position between the end of the bevel post 2 and the bevel post 1 after the crossbeam 2 is subsequently inserted into the insert ring 31, thus successfully welding and fixing the crossbeam 2 to the bevel post 1. The size of the foam block 5 is slightly larger than the size of the inner cavity of the bevel post 1, ensuring that after the foam block 5 is inserted into the inner cavity of the bevel post 1, it stays at the penetration position of the bolt 33 and will not slide down. In addition, the protective shell 6, the sealing cover 61, the sealing ring 62, and the elastic sheet 7 can all be made of protective and ductile materials such as plastic and rubber.

[0030] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
